I'm just refreshing and reconfiguring a laptop, prior to issuing it to a new user. I need to open MS Outlook in order to delete the old user account and add the new user account. Unfortunately the old user (absent) appears to have configured Outlook to use MS exchange settings at a third party provider (Mail.Ru:, a common free webmail service). The connection settings appear to be corrupted or blocked, with the result that Outlook will not even open fully. Currently Outlook tries to "load profile" for a period, before presenting a user & password form for the remote MS exchange server. Even though the old user details are auto-filled, they are either incorrect or blocked. Pressing either "next" or "cancel" simply causes the Outlook loading screen to disappear. Hence i can't even start Outlook in order to be able to edit anything. How do i get into Outlook, or is there a user data file somewhere that I can delete and effectively leave Outlook blank? My only option at this point appears to be to re-install MS Office completely?
